In May 202- Aoife Ni Riain discovers that she can open a portal to other places using the runestones she has been experimenting with as part of her university research. Cut to five years later and people are dying in Naperville Chicago. Others are disappearing. Good cop Maire Neumann is investigating and in her off time pursuing a hobby case, the disappearance of Aoife Ni Riain. The various plot threads combine into an evil conspiracy, a love story, a delightful fantasy and a gritty cop thriller all at once. Campbell writes vividly using metaphor and simile. Good book. ( )
